Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing stations, in particular to a lightweight aggregate pre-wetting silo for a concrete mixing station. Background Art

[0002] Lightweight aggregate is made of light coarse aggregate, light fine aggregate or ordinary fine aggregate, cement, water, admixtures and admixtures. It can be used as concrete, and its apparent density is not more than 1950kg / m3. Lightweight aggregate has the characteristics of porous and rough surface and strong water absorption. Therefore, the workability of its mixture is significantly different from that of ordinary concrete. Lightweight aggregate concrete mixture has good cohesion and water retention, but poor fluidity. If the fluidity is increased, the aggregate will float and easily separate. At the same time, due to the high water absorption rate of aggregate, part of the water added to the concrete will be absorbed by the light aggregate, and the remaining part will be used for cement hydration and give the mixture fluidity. Therefore, the water consumption of the mixture should be composed of two parts: one part is the water consumption for the mixture to obtain the required fluidity, which is called the net water consumption; the other part is the water absorption of the light aggregate in 1 hour, which is called the additional water consumption. At present, when lightweight aggregate is pre-wetted in the silo, it is often treated by direct immersion. In the immersion process, the lightweight aggregate is immersed in normal pressure water. The normal pressure water reaches an air pressure balance with the micropores of the lightweight aggregate, and it is difficult for the water to penetrate into the micropores of the lightweight aggregate and completely replace the air in the micropores of the lightweight aggregate. This is time-consuming and inefficient. In addition, the pre-wet silos on the market are not convenient for draining, which makes it inconvenient to discharge the material. Utility Model Content
